This isn't something I'm currently faced with by the way - I'm just researching as I've not found the 'right' way to do shown anywhere.  I've seen videos of guys just cutting the seal and pulling the fuse themselves, but I've not managed to find anyone describing the process of requesting the...

Because I've worked on the industrial side of things for over 20 years and now in the middle of a career change as personal circumstances have changed.

What is everyone doing to safely isolate when you are faced with a consumer unit change and there is no isolator between the CU and the supply cut out? I assume it Is a case of contacting the DNO to come out? How long does this take and what are the fees, etc? I've seen plenty of videos of...

I wonder if there is some kind of auto-transformer or step-up transformer that could regulate the voltage for you. I can't see it being a cheap solution but something might exist? The main issue I foresee would be switching of loads fluctuating the voltage. Might be worth looking into though.

Client who I'm talking to is the Financial Director of the business. Unsure if they're the building owner yet. I'll go into the finer details during the site visit. 

We're currently tendering for a project where the client has requested a number of DBs to be upgraded in a commercial building. The installation is around 5o years old. Site survey isn't until next week so we haven't been to look yet and we don't know what records they have or when it was last...

Just to add to this good answer, the inrush is probably what is tripping the breaker so changing this from a B32 to a C32 will likely prevent the tripping. Some people may say turn the amp on first, but I understand that this might cause pops, etc.  

Still have to pay the court fee though so I'd still recommend another last attempt to resolve prior to court.

I would say that this is not the kind of Client you want to continue working with, so don't waste time trying to save the relationship.  Write a pre-legal letter giving them an opportunity to make the payment (and offer to knock off the sum for 2 x appliance tests as a measure of goodwill)...

Thanks - the price seems to be in the same area as Trimble MEP. Any reasons why you went for this product and how long have you been using it for?

Just wondering what everyone is using as their preferred methods for cable calcs? Are you using Trimble MEP (previously Amtech) or an Excel template?  If anyone has any spreadsheets that they're willing to share then even better. Thanks

Sad but true.

It's called a C7 Power Cable. Have a look here 

I know, but I was still surprised. 

You need to consider the maximum current carrying capacity of the cable so assuming it is a 2 core x 1.5mm cable clipped direct, this is 27A, so your protection device in the Consumer Unit would need to be below this to protect the cable hence why @Evans Electric said to use a 16A MCB or...

I checked a client's property the other week and he was getting 249V in to the Consumer Unit!  Given that this is a single short run, I don't see why you wouldn't go up to 6mm as the cost isn't that different.  Either that or suggest a smaller protection device as they're unlikely to pull...

I've seen exactly what you're looking for installed in a Segro warehouse near Heathrow Airport and just PVC cables used. I'm pretty sure Segro wouldn't accept this if it wasn't allowed as they are a large warehouse developer.

Didn't think of that - it is a dual RCD so that's a good shout. Thanks

I moved in to a new build property last year. In the living area there are 2 radiators on one wall, one on the adjacent and then none at the other end and large patio doors so this leaves it very cold in winter.  I'm looking at electric fireplaces as an alternative to a new radiator.  There...
